According to the damage situation of the stinger Hitch Point structure which is welded by the thick high-strength steel plates during the practical projects, this paper carries out the overall ifnite element analysis of the stinger of pipelaying barge, laid pipelines and hull under typical operation condition, and local ifnite element of the damaged area. It performs the stress analysis of the components under maximum environmental load and operating load and low-frequency impact load analysis by using explicit analysis method ABAQUS/Explicit. It also discusses the reasons causing structure deformation and damage, and design optimization direction.
